Artificial Pancreas use application to calculate insulin doses

An “artificial pancreas” tested in nine hospitals in France that injects real – time calculated the appropriate dose of insulin through a mobile phone could change the lives of diabetics.

The system, called Diabeloop, combines three devices connected together by Bluetooth: an insulin pump and glucose sensor placed under the skin -both and are used by millions of patients around the world and Android phone with a specific application using a complex algorithm.

The phone may also transmit data permanently patient to a telemedicine center.

With this system, diabetics type 1 (insulin – dependent) no longer have to make difficult calculations to determine your insulin dose, which varies greatly depending on meals, stress, or hours of the day.

Also will avoid episodes of hypo- or hyperglycemia, ie lack or excess blood sugar.

The program is based on an algorithm “hypercomplex of 13 equations in 13 unknowns ” explains Sylvain Rousson, one of the engineers who developed it . “The idea is to calculate continuously and advance the rate of blood the patient will have within two hours to determine how much insulin needs immediately , ” he added.

The program is also able to provide by itself improvements in their functions, refine their calculations to better fit the patient and achieve a better result.

“We do not need to think or worry about whether we will be in hypo- or hyperglycemia” explains Marie-Claude Lehmann, one of the 45 “guinea pigs” who tested the device.
